Dug out some old cassettes of live broadcasts I made way back when and converted them to digital to play on a PC. One of them was a special on Glenn Miller from CKJY in their Big Band Music Of Your Life format. They must have had some special equipment or I got them on a good night for signal because it's still among the best sounding recording I made then. I have a few from WWWW, WJZZ, WQRS and WUOM that sound good, but not AS good.

I went looking for the station to see if by chance they were still around, only to find they only existed for two years: https://en.wikipedia.org/wiki/CIDR-FM

Kind of bummed, but it certainly dates the tape I have.
